About the origin of many Y-haplogroups a recent paper promises interesting contributions: "Huge study on Y-chromosome variation in Iran" (Grugni et al. 2012). Dienekes is singing about hg R in Iran: “This is especially true for haplogroup R where pretty much every paragroup and derived group is present, excepting those likely to have originated recently elsewhere”.He has to read the paper, and I too, but form the abstract:“The phylogeography of the main haplogroups allowed identifying post-glacial and Neolithic expansions toward western Eurasia but also recent movements towards the Iranian region from western Eurasia (R1b-L23) […]”.

I make you know that in the Table S1, where are the frequencies of the haplogroups of the 44 populations included in the PCA, only Italy/Sardinia data are unpublished. Why? I think that these scholars are going to publish a paper on Sardinia/Italy, and I think that we’ll look at finally where is the true origin of some haplogroups, including R1b but also R1a, as I think having demonstrated in these years.
